Abstract

Techniques for determining a status of a system update with a long latency may be provided. For example, the system may receive a request to update a value associated with an item offered by a merchant. The new value may be transmitted to one or more other computer systems, so that the new value can be updated in a master data store maintained by the one or more other computer systems. The new value can also be stored in a temporary data store associated with the system and the merchant may be informed that the new value was received and is being updated.

Claims

1. A computer-implemented method for updating a first value associated with an attribute of an item to a second value associated with the attribute of the item in a distributed system of computers, comprising:

receiving, by a first computer system of the distributed system of computers from a master data store, the first value associated with the attribute of the item;

displaying, by the first computer system to a user interface of a user device, the first value;

receiving, by the first computer system of the distributed system of computers, a first request to update the first value associated with the attribute of the item to the second value associated with the attribute of the item, the first request received via the user interface of the user device, and the first request transmitted by the user device via a communication network to the first computer system of the distributed system of computers;

transmitting the second value to a second computer system of the distributed system of computers, the second computer system configured to update the first value stored in the master data store and associated with the attribute of the item to the second value in the master data store, the update of the first value to the second value associated with a latency delay with respect to the transmitting;

calculating the latency delay with respect to the transmitting;

storing the second value in a temporary data store associated with the first computer system;

based at least in part on the calculated latency delay, enabling display of the second value, an estimated wait time corresponding with at least the calculated latency delay, and a notification about the second value to the user interface of the user device, the display of the second value corresponding to the temporary data store and not the master data store;

determining that the second value is different from the first value being updated;

transmitting a second request to the second computer system of the distributed system of computers, the second request requesting a master value from the master data store;

receiving the master value from the second computer system of the distributed system of computers, wherein the master value matches the second value; and

switching a source of the display of the second value to the master data store from the temporary data store.

2. The computer-implemented method of claim 1, further comprising:

upon determining that the master value matches the second value, determining that the master value was updated according to the first request to update the first value to the second value.

3. The computer-implemented method of claim 1, further comprising:

after storing the second value in the temporary data store, identifying a refresh request from a browser application, the browser application used to access a presentation of the item by the first computer system of the distributed system of computers; and

updating the notification to include the second value from the temporary data store.

4. The computer-implemented method of claim 1, wherein the first computer system performs an action, and the action includes providing notice to a web service of the second computer system of the distributed system of computers that indicates the latency delay in processing the update of the first value to the second value stored in the master data store.

5. The computer-implemented method of claim 1, wherein the first computer system performs an action, and the action includes updating the notification to include the estimated wait time.

6. The computer-implemented method of claim 1, further comprising:

receiving, by the first computer system, an inventory request to receive inventory information associated with a user of the user device, wherein the inventory information identifies items that the user offers to consumers.

7. The computer-implemented method of claim 1, wherein the second value is associated with a time that the second value was received, and further comprising:

comparing the time with a current time to determine a time difference;

determining that the time difference exceeds a threshold amount of time;

generating an alert that identifies the time difference; and

transmitting the alert to the user device, the transmission of the alert based in part on the time difference exceeding the threshold amount of time.

8. The computer-implemented method of claim 1, wherein the displaying of the first value for the item on the user interface of the user device corresponds to a merchant network page that is accessible to consumers.

9. The computer-implemented method of claim 1, further comprising:

upon updating the first value to the second value in the master data store, amending a markup language associated with the display of the second value and the notification to remove the display of the notification from the user interface.

10. The computer-implemented method of claim 1, wherein the second computer system implements one or more web services to update the master data store, and wherein the one or more web services process the update of the first value to the second value sequentially.

11. The computer-implemented method of claim 1, further comprising:

transmitting the notification via text message or email to the user device.

12. The computer-implemented method of claim 1, wherein the latency delay is based in part on a physical distance between the first computer system of the distributed system of computers and the second computer system of the distributed system of computers.

13. One or more non-transitory computer-readable storage media collectively storing computer-executable instructions that, when executed by one or more computer systems, configure the one or more computer systems to collectively perform operations comprising:

receiving, by a first computer system of a distributed system of computers from a master data store, a first value associated with an attribute of an item;

displaying, by the first computer system to a user interface of a user device, the first value;

receiving, by the first computer system of the distributed system of computers, a first request to update the first value associated with the attribute of the item to a second value associated with the attribute of the item, the first request received via the user interface of the user device, and the first request transmitted by the user device via a communication network to the first computer system of the distributed system of computers;

transmitting the second value to a second computer system of the distributed system of computers, the second computer system configured to update the first value stored in the master data store and associated with the attribute of the item to the second value in the master data store, the update of the first value to the second value associated with a latency delay with respect to the transmitting;

calculating the latency delay with respect to the transmitting;

storing the second value in a temporary data store associated with the first computer system;

based at least in part on the calculated latency delay, enabling display of the second value, an estimated wait time corresponding with at least the calculated latency delay, and a notification about the second value to the user interface of the user device, the display of the second value corresponding to the temporary data store and not the master data store;

determining that the second value is different from the first value being updated;

transmitting a second request to the second computer system of the distributed system of computers, the second request requesting a master value from the master data store;

receiving the master value from the second computer system of the distributed system of computers, wherein the master value matches the second value; and

switching a source of the display of the second value to the master data store from the temporary data store.

14. A first computer system for updating a first value associated with an attribute of an item to a second value associated with the attribute of the item in a distributed system of computers, the first computer system comprising:
